WRONG!!!! The reason you keep your woman on the left, is so you can get a better swing and therefore more momentum when you have to swipe the biatch upside the head! (with your right hand, of course )
Seriously, and o/t..I used to drag a 40 tonne artic around Europe, switching from one side of the road to the other quite frequently during the course of a week...(UK -> Mainland Europe -> back to UK etc) and never had any main problems.
One thing that is IMPERATIVE that you watch out for in France is their stupid "Priorite a Droit" rule, which means that in some cases you can be happily trundling down a main road when some twat pulls out of a small side road straight in front of you...after the resulting crash, you then find out that because there were no road markings to state otherwise, HE had right of way!!!
As for gear changes....my coach has the gear shifter on the RIGHT of my seat, and its a RIGHT HAND DRIVE coach!!
In any case, anyone who wants practice driving on the other side can just unclip their G25 Shifter and stick it on the other side of their wheel...that will help you get used to having the gear change on the 'wrong' side
